Unlike many words, I sound exactly like myself!

I can spun into gold I can be a man I can be the last Can you guess what I am?

Tread in the tulips, Nice and light, Swan lake style, Add some height

I’m born from something whole but never stay that way. I glitter like treasure yet promise only blood if you’re careless. I remember the shape I used to be, but now I travel alone, a splintered echo of a former self.
